Until now, nano-structuration, hetero-interface, and surface doping are the most widely used three strategies to combine battery-type and capacitive charge storage in electrode materials.
More specifically, electrode materials with both battery-type and capacitive charge storage are traditional electrode materials for metal ion batteries in their bulk states, and the capacitive charge storage is apparent only with rationally engineering the architectures of electrode materials.
The design of cathode mainly focuses on increasing proton storage to enhance capacity. Correspondingly, the focus on the negative electrode is to improve the cyclic stability of materials and prepare long-life materials.
Third, both capacity and cyclability between negative and positive electrode materials with combined battery-type and capacitive charge storage should be matched when designing full cell devices (such as metal ion hybrid capacitors and metal ion full battery) [ , , ].
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.
Recently, electrode materials with both battery-type and capacitive charge storage are significantly promising in achieving high energy and high power densities, perfectly fulfilling the rigorous requirements of metal-ion batteries and electrochemical capacitors as the next generation of energy storage devices.
